DC arc plasmatron and method of using the same

The present invention relates to a plasmatron structure for heating working gas in a DC arc discharge at the atmospheric or lowered pressures and can be used for different electronic, engineering, or vehicle-building industries and for medicine. An object of the invention is to provide improved effectiveness of process gas activation and increased completeness of plasma-chemical reactions. These objects are achieved in a DC arc plasmatron comprising a rod cathode, a nozzle anode having a body member and a through axial orifice, a power supply unit connected to both electrodes, and a gas system for feeding plasma-forming gas into inter-electrode space and supplying suitably selected technologic gas or gas mixture into the anode orifice through an internal opening communicating with said orifice and positioned between its inlet and outlet parts. In the plasmatron according to the invention, said opening is configured as a continuous circular axial gap between said parts of said anode orifice, while the size of said gap can be smaller or larger than the diameter of the inlet part of said anode orifice and the diameter of the outlet part of said anode orifice can also be smaller or larger than the inlet part of said anode orifice. In addition the inventive plasmatron can be successfully applied in vacuum conditions to extend lifetime of the activated process gas and to provide the clean treatment procedure.
